Spontaneous eruptive disseminated lobular capillary haemangioma.

Lobular capillary haemangioma (LCH), previously known as pyogenic granuloma, is a benign vascular tumour of the skin or mucosa. We report a patient with spontaneous eruption of LCH, a rare occurrence, which resolved probably due to reverse koebnerisation.

Lichen planus triggered by COVID-19 vaccination: A case series.

Lichen planus, an autoimmune inflammatory condition, has been linked to medications, vaccinations, and infections. Several clinical studies have shown that majority of vaccines trigger a Th1 response, which raises the blood levels of IL-2, TNF & IFN, and may be linked to the development of lichen planus. It has recently been documented to happen with mRNA-based COVID-19 vaccinations, especially the Pfizer/BioNTech vaccine. We present a case series of lichen planus that appeared after receiving the COVISHIELD vaccine from Oxford-AstraZeneca. In order to rule out any further potential triggers, like recent infections, prior drug use, smoking, dental treatments, etc., a thorough history was collected in each instance. Skin biopsies were used to confirm each case's diagnosis. In nearly all of the cases, skin biopsies revealed typical dermatopathological features of lichen planus.

Association between COVID-19 infection and herpes zoster: A case series.

Herpes zoster (HZ) is a manifestation of the reactivation of latent varicella zoster virus (VZV) infection in the dorsal root ganglion. The occurrence of HZ has been reported in association with COVID-19. Herein, we describe 10 cases who developed classic HZ within 2-3 weeks of acquiring COVID-19 infection. The triggers in these patients could be severe stress (related to quarantine issues, fear of hospitalisation and death) immune dysregulation and systemic steroid therapy in treating COVID-19. The clinical patterns and therapeutic responses observed were similar to HZ in immunocompetent persons. Increased expression of NKG2A on NK and CD8+ T cells has been proposed as a pathophysiologic mechanism in triggering HZ at the molecular level in COVID-19 patients. Primary physicians should be aware of this association to counsel and treat such patients appropriately, as initiating early treatment could minimise the risk of complications like postherpetic neuralgia.

Segmental neurofibromatosis with Lisch nodules.

Neurofibromatosis (NF) is an inherited neuroectodermal abnormality that primarily affects the growth of neural tissues, and Riccardi classified it into eight types. Segmental neurofibromatosis, which is a rare form of neurofibromatosis, is classified as type 5. We report a case for very unusual presentation of segmental NF with unilateral lisch nodules and uncommon sites involving the scalp. Moreover, we could find only one case report of segmental NF with lisch nodules in the literature and could not find any case report involving the scalp.

Tuberous xanthoma with cardiac failure in a child.

A 14-year-old girl presented with gradually progressive breathlessness for 3 weeks. On evaluation, it was found that she had left ventricular hypertrophy and nonprogressive R wave in ECG. An echocardiogram revealed aortic stenosis and severe left ventricular dysfunction.Computed Tomography (CT) imaging showed aortic annulus calcifications causing aortic stenosis. Over three years she had gradually developed asymptomatic cutaneous swellings over the small and large joints of the extremities suggestive of tuberous xanthomas. Skin biopsy revealed scattered foamy macrophages in the upper dermis and cholesterol clefts. Her lipid profile showed raised total cholesterol and low-density lipoprotein levels. With the above clinical, histological, and laboratory findings she was diagnosed as a case of familial homozygous hypercholesterolemia with tuberous xanthomas and cardiac failure. She was started on statins, ezetimibe, and other anti-failure measures. We present this case for its rarity. Early diagnosis of this condition based on skin findings, could have prevented cardiac failure by initiating early appropriate treatment.

A descriptive study of onychoscopic features in various subtypes of onychomycosis.

Background: The diagnosis of onychomycosis is usually clinical and is confirmed by 40% KOH examination. A diagnostic dilemma occurs when KOH examination is negative despite strong clinical suspicion. Dermoscopic evaluation of the nail is referred to as onychoscopy. We attempted to assess the dermoscopic findings in Onychomycosis positive with KOH examination. Methods: A cross sectional study was conducted in a tertiary care center including 122 patients with clinical suspicion of onychomycosis with KOH positivity. After assessment of risk factors and gross nail examination, onychoscopic examination was done to identify the presence of the specific features. Results: Primary findings of onychoscopic examination were 'spiked pattern' in 80.3% subjects, of which 95 were distal lateral subungual onychomycosis (DLSO), 8 of total dystrophic onychomycosis (TDO). True leukonychia was seen in the single patient of proximal subungual onychomycosis (PSO) and pseudoleukonychia in the single patient of white superficial onychomycosis (WSO). Distal irregular termination was observed in 23% of subjects - 8 from DLSO and in all 20 patients of TDO. 'Ruin appearance' was observed in all 20 patients of TDO, 56 patients with DLSO and not seen in other types of onychomycosis (OM). Presence of spiked pattern, Longitudinal striae, Distal irregular termination and Ruin appearance were found to be statistically significant (p < 0.001). Conclusion: In suspected onychomycosis, specific onychoscopic findings such as Spiked pattern, Longitudinal striae, Ruin appearance and Distal irregular termination can be used as supporting evidence for diagnosing onychomycosis clinically and initiating antifungal therapy if mycological testing is unavailable or negative.

An interesting case of nevus flammeus with loss of vision and hemiparesis.

Nevus flammeus is the most common benign congenital capillary malformation, often known as a port-wine stain. Sturge-Weber syndrome (SWS) is a congenital, sporadic, nonfamilial disease characterized by intracranial and ophthalmic vascular anomalies and nevus flammeus. It usually manifests as developmental delay, learning problems, paralysis, seizures, glaucoma and attention deficit, and hyperactivity disorder. A 29-year-old male patient presented with a reddish patch over the face since birth. He was found to have hemihypertrophy of face, hemiparesis of right limbs, and low intelligence quotient. On ophthalmic examination, the patient was found to have glaucoma and only perception of light in the left eye. Computed tomography brain showed atrophy of the left cerebral hemisphere and calcifications in the left frontal, parietal and occipital regions. With these findings, he was diagnosed as SWS type I. A multidisciplinary approach was followed for patient evaluation and management. This case also highlights the irreversible sequelae of this rare phacomatosis.

A rare case of disseminated superficial porokeratosis-Case report.

Porokeratosis is a keratinization disorder characterized by hyperkeratotic sharply demarcated plaques with central atrophy and histopathologically, by cornoid lamella. A 30-year-old male presented with multiple pruritic dark raised skin lesions over the trunk, face, and upper limbs for past 3 years. Cutaneous examination revealed hyperkeratotic annular plaques with raised margins over face, trunk, and arms. Histopathology revealed marked hyperkeratosis with irregular acanthosis and papillomatosis. Vertical parakeratotic foci and focal hypergranulosis were seen. Hence, a diagnosis of disseminated superficial porokeratosis was made. We present this rare case which may have association with systemic disease, immunosuppression, and malignant transformation.

Syphilis D' Emblée: A case series of the great masquerader.

Syphilis, a chronic infectious disease caused by Treponema pallidum subspecies pallidum, progresses through three arbitrary stages resulting in varied clinical manifestations. The aberrant presentation of syphilis in the secondary stage without any clinical evidence of the primary stage is referred to as syphilis d' emblée. Here we report a series of six cases in male patients. Five out of six patients presented with multiple, non-pruritic, macular palmar, and/or plantar lesions. One patient had typical facial and perianal lesions of condyloma lata. The diagnosis was confirmed by a reactive VDRL with titers ranging from 1:16 to 1:64 and a positive Treponema pallidum hemagglutination assay (TPHA). Syphilis being a great imitator can present in different ways without a typical history of primary chancre following sexual exposure, and can mimic many dermatological disorders in its secondary stage. Unless physicians have a high index of suspicion, the diagnosis may be missed. Early identification aids in prompt initiation of therapy and prevention of disease progression to chronic stages and systemic manifestations.

Lax skin and blurring of vision- A case report of pseudoxanthoma elasticum.

Increased laxity of the skin can be caused by aging, significant weight loss, or defects in the elastic tissue. A 38-year-old female presented with increased laxity of the skin over the neck, thighs, and abdomen for 6 years, associated with headache and blurring of vision for a week. On cutaneous examination, prominent skin folds, laxity, and wrinkles were noted over the neck, abdomen, thighs, and groin, with yellowish papules along the neck creases. Ocular examination revealed features suggestive of angioid streaks. Skin biopsy showed fragmented elastic fibers and intervening calcium deposits on Verhoeff Van Gieson and Von Kossa stains. Based on these findings, a diagnosis of pseudoxanthoma elasticum (PXE) was made. The patient was started on oral and topical sunscreens and eye protection and advised regular follow-up. Diagnosing the condition early based on skin findings can help prevent further multi-system manifestations by taking appropriate preventive measures as this condition is progressive and has no cure.

A descriptive study of the clinical and etiological profile of balanoposthitis.

BACKGROUND: Balanoposthitis is defined as an inflammatory condition of glans penis and prepuce. There are wide variety of etiologies including both infectious and noninfectious conditions. This study attempts to throw light on information regarding clinical and microbiological aspects of balanoposthitis. OBJECTIVES: To study various clinical patterns, etiologies, and predisposing factors of balanoposthitis. METHODOLOGY: A descriptive study was undertaken on 106 cases who presented to sexually transmitted disease (STD) clinic with balanoposthitis between November 2017 and April 2019. A detailed history, physical examination, and investigations like KOH mount, leishman staining, gram staining, dark field microscopy, cultures, and other investigations were done wherever indicated. The data collected was tabulated and analyzed. RESULTS: In our study, infectious etiology was the most common and was found in 77.36% cases. About 13.41% of cases with infectious balanoposthitis had multiple etiological agents. Noninfectious etiology was found in 22.64% cases. The most common infectious cause of balanoposthitis was candida, noted in 59.76% cases, followed by herpes simplex virus (19.51%), human papilloma virus (13.41%), and scabies (8.54%). Among noninfectious etiologies, adverse drug reaction (4.72% of total cases) was the most common, followed by lichen planus (3.77%) and psoriasis (3.77%). There was significantly higher incidence of phimosis in diabetic patients with candidal balanoposthitis. CONCLUSION: Identifying the etiology facilitates early treatment and hence reduces the infectivity and transmission of disease and also the disease complications like phimosis. In addition, multiple infectious etiologies should always be kept in mind while evaluating STDs.

Cefotaxime induced generalized bullous fixed drug eruption - A case report.

Fixed drug eruption (FDE) is the most common cutaneous adverse drug reaction. Cefotaxime, a broad-spectrum third-generation cephalosporin, appeared to be a safe and effective therapy in greater than 90% of infections including cellulitis, abscesses and necrotizing ulcers of the skin and subcutaneous tissues but here we report a rare case of 36 years old female patient developed generalized bullous FDE after intravenous administration of Cefotaxime.

Decrease in "Hamilton Rating Scale for Depression" Following Isotretinoin Therapy in Acne: An Open-Label Prospective Study.

BACKGROUND: Acne is a common disorder among adolescents and young adults causing a considerable psychological impact including anxiety and depression. Isotretinoin, a synthetic oral retinoid is very effective in the treatment of moderate to severe acne. But there have been many reports linking isotretinoin to depression and suicide though no clear proof of association has been established so far. OBJECTIVE: To determine whether oral isotretinoin increases the risk of depression in patients with moderate to severe acne. MATERIALS AND METHODS: One hundred and fifty patients with moderate to severe acne were treated with oral isotretinoin 0.5 mg/kg/day for a period of 3 months. Their acne and depression scoring was done at baseline and then every month for the first 3 months and then at 6 months. RESULTS: We found that the acne scoring reduced from 3.11 ± 0.49 to 0.65 ± 0.62 (P = < 0.001) at the end of 3 months. Also, the depression scoring decreased significantly from 3.89 ± 4.9 at the beginning of study to 0.45 ± 1.12 (P < 0.001) at the end of 3 months. Both the acne and depression scores continued to remain low at the end of 6 months at 0.5 ± 0.52 (P = < 0.001) and 0.18 ± 0.51 (P = < 0.001), respectively. CONCLUSIONS: Our study proves that oral isotretinoin causes significant clearance of acne lesions. It causes significant reduction in depression scores and is not associated with an increased incidence of depression or suicidal tendencies.

Autosomal dominant hearing loss resulting from p.R75Q mutation in the GJB2 gene: nonsyndromic presentation in a South Indian family.

Mutations in the GJB2 gene encoding the gap junction protein Connexin 26 have been associated with autosomal recessive as well as dominant nonsyndromic hearing loss. Owing to the involvement of connexins in skin homeostasis, GJB2 mutations have also been associated with syndromic forms of hearing loss showing various skin manifestations. We report an assortatively mating hearing impaired family of south Indian origin with three affected members spread over two generations, having p.R75Q mutation in the GJB2 gene in the heterozygous condition. The inheritance pattern was autosomal dominant with mother and son being affected. Dermatological and histopathologic examinations showed absence of palmoplantar keratoderma. To the best of our knowledge, this is the first report from India on p.R75Q mutation in the GJB2 gene with nonsyndromic hearing loss.

Abrikossoff's Tumor: An Unusual Presentation.

Abrikossoff's tumor or granular cell tumor is an infrequent benign neoplasm, first described by the Russian pathologist Abrikossoff in 1926. The neoplasm can affect all parts of the body with head and neck areas affected in 45-65% of patients. More than half of the head and neck lesions are localized to the oral cavity, especially the tongue. An aggressive malignant form of granular cell myoblastoma that metastasizes is rare. The treatment of choice of Abrikossoff's tumor is local surgical excision with a wide margin. Here, we present a case of Abrikossoff's tumor, occurring in the upper arm, presenting as a panniculitis-like lesion.

Squamous cell carcinoma of penis with bullous pemphigoid masquerading as lymphogranuloma venereum.

We report a case of a 60-year old unmarried male who presented with multiple ulcers and foul smelling discharge from the groin since 4 months and multiple tense bullae over the trunk of 1 month duration. Groove sign was present. Investigations for lymphogranuloma venereum (LGV) and other sexually transmitted diseases were negative. Histopathology from the ulcer in the groin and growth in the penis revealed squamous cell carcinoma (SCC). Skin biopsy of bulla was diagnostic of bullous pemphigoid (BP). We report a rare case of SCC masquerading as LGV with BP occurring as a paraneoplastic phenomenon.

Woolly hair nevus: a rare entity.

Woolly hair nevus is a rare non-hereditary focal condition characterized by unruly and tightly coiled hair. It can appear in childhood or adolescence and may be associated with epidermal or melanocytic nevus. Patients presenting with woolly hair must be examined completely to rule out cardiofaciocutaneous and Noonan syndrome.

Therapeutic efficacy and safety of propylthiouracil in psoriasis: an open-label study.

BACKGROUND: Psoriasis is a common hyperproliferative disorder of the skin associated with significant morbidity. Most of the drugs used in psoriasis provide only a temporary relief, whereas they are riddled with potential toxicities and cost concerns. Hence, there is a constant need to explore newer, effective, orally administered, and cost-effective drugs with minimal adverse effects. In this scenario, propylthiouracil (PTU), an antithyroid thioureylene has been shown to be effective in psoriasis which satisfies the above criteria. AIM: The objective of our study is to assess the clinical efficacy of PTU in psoriasis. METHODS: A total of 25 patients with plaque psoriasis were treated with oral PTU for 12 weeks. Clinical response was assessed using the "Psoriasis Area and Severity Index" (PASI) score. Routine blood analyses and thyroid function tests were carried out periodically during the study. RESULTS: Oral PTU produced significant clearing of lesions at 6 weeks and 12 weeks of the study period in all patients, as demonstrated by the reduction in PASI scores (33.9% in 6 weeks and 74.1% reduction in 12 weeks). Four patients experienced near complete clearing of the lesions. One patient developed mild elevation of liver enzymes which reversed on withdrawal of PTU. None of the patients had hypothyroidism or cytopenias. CONCLUSION: PTU significantly clears the lesions in psoriasis with minimal adverse effects. Hence, it can be considered as a therapeutic option in psoriasis, especially when the standard drugs cannot be used due to their toxicities or forbidding cost.
